PULVERIZING MACHINE.

Application filed April 29, 1927. Serial N0.*187,524.

This invention relates to a certain new and useful IIHPIOXQIDGIlt in pulverizmg or crushmg machines.

My invention has for its chief object theprovision in a machine of theclass stated of a pivotally swingable grinding-plate and readily operable means for conveniently, efficiently, and positively shifting the plate adjustably relatively to the hammeranechanism of the machine as may be desired in the particular grinding or pulverizing operations being carried on.

And with the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combination of parts hereinafter described and pointed out inthe claims. I

In the accompanying drawing,

Figure 1 is a fragmental side elevational view, partlyvbroken away and in section, of a grinding or pulverizing machine embodying my invention;

Figure 2 is also a fragmental side elevational view of the machine; I

Figure 3 is a detail fragmental sectional view of the machine; and c Figure 4 is a partly broken end viewof the machine. 1 i 7 Referring now more in detail and by reference characters to the drawing, which illustrates a preferred embodiment of, and which shows merely such parts of the entire machine as are directly associated with, my present invention (a fuller or more complete illustration of a machineofthe type to which this invention especially pertains is given in the application of ET. Roebke for patent for pulverizing machine, Serial No. 174,8 18, filed March 12, 1927) 1 designates an end wall and 2-, 2, the spaced side walls of the base A of the casing or shell of the machine, which is adapted to rest upon a floor, foundation, or other place of support.

B designates the main shaft of the machine, which is journaled for rotation on boxes 3 disposed upon the base side walls 2, and G designates the hammer mechanism, the latter preferably and in the present illustration in cluding a spider 4 mounted on and suitably keyed to shaft B and ring-hammers 5 supported by the spider 4 both for rotation with and relatively to shaft B, as in said application of E. T. Roebke more fully described.

Suitably disposed and fixed within the base A. for cooperation with the hammer mechanism C, is a grinding-surface or grate D,and

forming substantially a continuation of the grate D and suitably pivoted, as at 6, upon I provided upon its outer face with outwardly presented preferably spaced lugs or bosses 7, 7, having flat end faces, as at 8, obliquely disposed to the base end wall 1.

In operative location relatively to the plate E, the base side walls 2 are formed with out-- wardly presented bosses or lugs 9 aligned transversely of themachine and apertured, as atlO, in registration.

Fitted for rotatory movement in the respective bosses .9, are cylindrical bushings or bearings 11 having shaft-openings 12 also aligned transversely the machine, but eccentrically disposed, relatively to the apertures 10 of bosses 9, each of the members or bearings 11 being laterally and annularly flanged at its outer end and thereby formed or provided with a disk or ring 13 adapted to abut at its inner end face fiatwise upon the outer end face of the respective boss 9, as best seen in Figure 3. Preferably, for purposes the plate bosses 7, is a shaft 17 preferably of non-circular or rectangular section through-' out, except at its opposite ends 18, at which ends'the shaft 17 is of circular section and is disposed for support in the eccentric apertures 12 of the bearing-members 11, as best seen inFigure 3.

As best seen in Figure 1, the concave E rests at its lugs 7 upon and is thus supported at its free or lower end by the shaft 17 for co-operation with the hammer-ringsfi; To shift the concave or plate E relatively to the rings 5 to meet the conditions or requirements of the crushing or pulverizing operations being carried on, the taps 16 are removed and the rings or disks 13 then, by means of a' spanner-wrench or other suitable tool (not shown) engaged with openings 15 thereof, rotari y actuated in one or the other direction, vith the result that the shaft 17 will be sh fted obliquely relatively to the lugs 7 and the plate or concave E consequently shifted pivotally toward or from the hammers 5.

Thus, in a simple, facile, and convenient manner, adjustments of the concave E may be effected to meetgrinding or pulverizing requirements.

Pivotallv t'astened, as at 19, to the plate E and projecting endwise therefrom through the base end-wall 1, is a bolt 20, disposed upon the threaded free end of which, are nuts or the like 21 adapted for impingement upon the base wall 1. to retain the plate E against the shaft 17 in any of its adjusted positions.

I am aware that changes in the form, construction, arrangement, and combination of the various parts of my new adjustable grinder plate maybe made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patout is:

1. In combination, in a machine of the class described, a casing, bosses oppositely presented outwardly from the side walls of the casing, said bosses having circular apertures aligned transversely of the machine, a hammer-mechanism mounted for operation within the casing, a grinding-plate mounted for adjustable movement pivotally within the casingin co-operative relation to the hammcnmechanism,and means for adjustahly shifting the plate pivotally relatively to the hammer-lurchanism, said means including cylindrical bushings mounted for rotatory movement in-the apertures of the bosses and having openings aligned transversely of the machine and eccentrically disposed to the apertures of the bosses, spaced lugs projecting from the outer face of said plate, each of said lugs having a flat end-face obliquely disposed to the end wall of the casing, and a shaft extending transversely of and through the easing and having its ends disposed in the openings of the bushings, the shaft intermediate its ends being of non-circular section for flatwise plate-sup uirting engagement with the flat end-faces of said lugs, said shaft; being shifted obliquely relatively to the lugs and said plate being shifted pivotally on rotatory actuation of said bushings.

3. In combination, in a machine of the class described, a casing, bosses oppositely presented outwardly from the side walls of the casing, said bosses having circular apertures aligned transversely of the machine, a hamnier-mcchanism mounted for operation within the casing, a grinding-plate mounted for adjustable movement pivotally within the casing in co-operative relation to the hammer-mechanism, and means fonadjustably shifting the plate relatively to the hammermechanism, said means including cylindrical bushings mounted for rotatory movement in the apertures of the bosses and having openings aligned transversely of the machine and eccentrically disposed to the apertures of the bosses, spaced lugs projecting from the outer face of said plate, each of .aid lugs having a flat end-face obliquely disposed to the end wall of the casing, a shaft extending transversely of and through the casing and having its ends disposerl in the openings of the bushings, the shaft intermediate its ends being of non-circular section for flatwise platesupporting engagement with the flat end-faces of said lugs, and tool-cngageable and bushing-actuated disks fixed on the bushings and abutting the outer end face of said bosses, said shaft being shifted obliquely relatively to the lugs and said plate being shifted pivotally on rotatory actuation of said bushing-disks.

In testimony whereof, I have signed my name to this specification.

JOSEPH 'IEIPEL.
